YoLink Smart Water Leak Protection System for Home: Bulldog Valve Robot, Smart Valve Controller, Leak Sensors, Hub

About this item

• EXTREME DISTANCE, UNMATCHED: wireless connectivity over a quarter-mile in open environments, excellent ability to penetrate obstacles (including metal!), and remarkably extended battery life, made possible by advanced LoRa (Long-Range) and low-energy innovations.
• DON'T TRY THIS WITH WiFi! YoLink devices do not use your WiFi, while typical smart devices do and can bog down your network and can even present a security risk. Our 923.3 MHz Chirp Spread Spectrum technology allows you to place sensors on other floors and even in other buildings, through concrete and even metal, where WiFi can't reach or is spotty.
• THAT WAS EASY! Simple, no-plumber-required, DIY installation (you can do it!), installs in minutes. PLUG, PLUG & PLAY Hub installation (plug it directly into your router), and SET IT & FORGET IT water leak sensors.
• DON'T JUST DETECT, PROTECT: Everything you need to start your smart water leak protection system! State-of-the-art smart water leak sensors and automatic water shut-off, even if the internet is down and the power is out, thanks to our unique Control-D2D device-to-device pairing.
• KNOW NOW! You have many options for being notified of device activity! Receive a text, receive an email, receive a phone push notification (including Apple phone "Critical Alert" severe weather/Amber alert type notifications that will activate your phone even if in silent mode. Android phones offer similar functionality, depending on phone manufacturer). SMS messages are limited to the total of 5 times each device plus 5. A hub and three sensors provides you with 25 free SMS per month.
